| Abstract: | This thesis will investigate the realisation of an RFID signal processing system to determine an RFID tag’s location using the MUSIC algorithm. The RFID signal processing system can be a replacement for Electronic Article Surveillance for retail at the entrance of stores. The optimal implementation of the MUSIC algorithm on an embedded system using hardware and software codesign is the main goal for this thesis. A System-On-Chip (SoC) is used to implement the processing blocks of the MUSIC algorithm: covariance matrix calculation, eigendecomposition and localization. These processing blocks are implemented on the processing platform that is most well suited for the timing and resource requirements. The platforms chosen are an FPGA for the covariance matrix calculation to adhere to the hard deadline of the input processing, and an ARM CPU for eigendecomposition and localization for the usage of the integrated Floating Point Unit(FPU) and the appropriateness to use a high level programming language to reduce the development time. The implementation satisfies the requirements of a total processing chain latency of 0.5 seconds, has an position estimation accuracy of 8 cm and is implemented within the available resources. |
